The earlier Mirage/SpaceStar up to 2017 model had 180mm inner-diameter rear brake drums, while 2017 and later models had 203mm drums.

Brake shoes for the earlier 180mm drums are Mitsu part Nr. OE 4600346, and suitable replacements from the manufacturer A.B.S are part number 9357. I did not find any other aftermarkt shoes for the 180mm drums.

Brake shoes for the later 203mm drums are very easily available, a quick search came up with more than 15 brands.
Some of the more popular manufacturers include:
ATE, part Nr. 03.0137_0530.2
TEXTAR, part Nr. 91082000
HELLA, part Nr. 8DB_355022-301

I cant wait till Blistein makes shocks/struts for the Mirage or other companies that can do something better than the Marshmallow OEM ones in the US market. Even the UR sway bar is still out of reach for the US market :/
